****************************************************************


***************************  List of  substantive changes from 3.2:

1. Increased support for Holdings. See http://www.loc.gov/standards/mods/v3/mods-holdings.html
2. Increased support for rights schemas: extensibility mechanism added to accessCondition to allow for other more detailed rights schemas (e.g.
CDL.s).  
3. Allow typeOfResource to be empty.
4. Add attribute 'authority' to <frequency> under <originInfo>.
5. Add under <recordInfo>, a new element <descriptionStandard> with an authority attribute, e.g. 
    <descriptionStandard authority="marcdescription">rak</descriptionStandard>.
6. Add under hierarchicalGeographic (under subject):  extraterrestrialArea, citySection. 
7. Add Xlink attribute to physicalLocation.
8. Add  additional enumerated values for authority under <language>: ISO 639-3 and RFC4646.


***************************  Non-substantive but notable changes.

1. For the 'xml:' namespace the schemaLocation="http://www.w3.org/2001/xml.xsd" is changed to  schemaLocation="http://www.loc.gov/mods/xml.xsd".
2.  For the 'xlink:' namespace the schemaLocation="http://www.loc.gov/standards/xlink.xsd" is changed to                                            schemaLocation="http://www.loc.gov/standards/xlink/xlink.xsd".
3. Attribute declarations are substantially consolidated. 
4. References to authority lists removed.

******* Group definition. 

This forms the basis of the mods record definition, and also relatedItem. The difference between a MODS record and a relatedItem is that mods requires at least one element and relatedItem does not. The group definition is used by both, where relatedItem says minOccurs="0" and for the mods record definition minOccurs="1" (default).
